A 36/240 V phase transformer, belonging to a phase measured from the no-load (idle) run and short-circuit test. values are given in the table below. High voltage by applying rated voltage to the low voltage winding (The winding ends were left unloaded and the results of the no-load test results were obtained. By applying nominal current to the high voltage windings, the low voltage windings were short-circuited, and the results of the short circuit test were obtained. In direct current test 1 V direct voltage is applied to the low voltage winding, and the transformer draws 500 A direct current. All equivalent Calculate the circuit elements as moved to the low voltage side.
Idle run test:
Voltage : 36V Power : 68W Current : 2,8A
Short circuit test:
Voltage : 15V Power : 325W Current : 42,2A
Which transformer is used for welding application? Explain the operation in detail with diagram.
